Parallax Scrolling Interface research based on Fitts' law

Parallax Scrolling Interface is being widely used with the popularization of computers touch-screen. Using simple design patterns and less development cost, developers can create perfect 3D visual effects with this kind of interface. Surprisingly, very little research about parallax Scrolling interface has been done. This paper addresses this need through two separate studies. First, a methodological study analyzes the form and technical principles of parallax scrolling, dissecting the main characteristics based on aesthetic and visual thinking theory. Second, a performance evaluation study builds performance evaluating model based on Fitts' law, which can summarize the problems of this technology and find its solutions. The results of these two studies suggest that parallax scrolling Interface has five technical limitations, and reasonable user experience design can effectively avoid these restrictions.
